Abstract: There are numerous examples of noteworthy pre-Columbian geotechnology in the Americas. These include earth mounds, stone temple pyramids, pile foundations, roads, retaining walls, terraces, irrigation structures, and small dams. They exhibit well-conceived designs and organized construction. Some investigators speculate that these sophisticated works reflect unrecorded technology from the Old World or possibly extra-terrestial intervention. However, the responsibility can be found in both indigeneous, ingeneous responses to local social and economic problems as well as well-organized community efforts. The lack of a formal system of logic, mathematical computation, and written communication inhibited the development and interaction of the embryonic technologies. Their decay was completed by the European conquest.
